maven 手动构建项目

maven 手动构建项目

在空目录下面：

D: est>mvn -B archetype:generate -DarchetypeGroupId=org.apache.maven.archetypes -DgroupId=com.stono -DartifactId=my-app

第一次会下载一些jar包，第二次输出：

会创建my-app，文件：

D:.
|   pom.xml
|
---src
    +---main
    |   ---java
    |       ---com
    |           ---stono
    |                   App.java
    |
    ---test
        ---java
            ---com
                ---stono
                        AppTest.java

pom.xml和App.java文件都中规中矩；

但是pom.xml必须手动修改一下：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

mvn compile 编译

mvn package 打包

mvn install 安装

mvn clean 删除

mvn clean package -U  强制更新依赖，删除那些updated文件 

mvn clean package -o offline编译模式，只使用本地仓库
